Neuromotor Task Training (NTT) and Nintendo Wii Fit Training (Wii training) are both task-based interventions used to improve performance in children with motor coordination problems. The aim of this study was to compare the efficacy of these two interventions on the motor performance, isometric strength and cardiorespiratory fitness (aerobic and anaerobic capacity) of children with Developmental Coordination Disorder (DCD) attending mainstream schools in a low-income setting. A pragmatic, quasi-experimental study design was utilized. Children between the ages of 6-10 years, who scored at or below the 16th percentile on the Movement Assessment Battery for Children-2 (MABC-2) and whose teacher reported a functional motor problem, were allocated to either NTT (n=37) or Wii training (n=19) groups depending on school of attendance. The MABC-2, a hand-held dynamometer, the Functional Strength Measure, the Muscle Power Sprint Test and the 20m Shuttle Run Test were used to assess performance at baseline and after the intervention. The main findings show that the mean motor performance scores of both groups improved over the study period. However, significant differences in improvement were detected between groups, with the NTT group showing greater improvement in motor performance, functional strength and cardiorespiratory fitness. No improvements in isometric strength were seen in either group. The Wii training group showed significant improvement in anaerobic performance. This study provides evidence to support the use of both the Wii Training and NTT for children with DCD. However, in comparison to Wii training, the NTT approach yields superior results across measures of motor proficiency, cardiorespiratory fitness and functional strength. The decision to use either approach may be influenced by resources and time constraints.
